brush - brush handle alpha# - alpha level of brush |
|
Sets the alpha level of a brush. The alpha# value should be in the range 0-1. The default brush alpha setting is 1. The alpha level is how transparent an entity is. A value of 1 will mean the entity is non-transparent, i.e. opaque. A value of 0 will mean the entity is completely transparent, i.e. invisible. Values between 0 and 1 will cause varying amount of transparency accordingly, useful for imitating the look of objects such as glass and ice. An dxBrushAlpha value of 0 is especially useful as Blitz3D will not render entities with such a value, but will still involve the entities in collision tests. This is unlike dxHideEntity, which doesn't involve entities in dxCollisions. |
